Rutting Prediction Model of Asphalt Mixture Based on the Triaxial Repeated Load Test

Table 1

Error ratios and residual sum of squares of simulated and measured rutting depths.

Type of mixture	Error ratio (%)	Residual sum of squares (%)
SK-90 asphalt mixture	8–27	5.00
SBS modified asphalt mixture	5–26	8.74
DCLR modified asphalt mixture	8–35	7.36
Composite DCLR modified asphalt mixture	8–34	8.27

Note. The error ratio is the ratio of the difference between the predicted and experimental values of rutting depth, and the residual sum of squares is the discretization degree of the fitting curve between the predicted and experimental values of rutting depth.
